Type A differential relays for motor load break

Releele de prevenire a punerilor la masă tip RESYS M40 sunt asociate cu dispozitive de declanşare cu telecomandă (întreruptoare automate),astfel permiţând următoarele funcţii:
• protecţia împotriva contactelor indirecte
• limitarea curenţilor de punere la masă
Releele monitorizează de asemenea instalatiile electrice când sunt folosite ca relee de semnalizare
